She may be an Oscar-winning movie star, but unless she's on the red carpet, she really doesn't bother glamming up!

On Tuesday afternoon Natalie Portman jetted out of Los Angeles International Airport, and the 33-year-old actress rolled solo and kept it super casual when X17 photographers snapped her picture.

Portman was on her way to China for the 17th Shanghai International Film Festival, and she'll be joined by fellow stars Nicole Kidman, Hugh Grant and Hayden Christensen. Kidman opened the fest on Saturday, and Portman is scheduled to close it.
